Boyle told The Sun: "We had to get permission for all the songs in the show. Cameron Mackintosh gave us permission for 'I Dreamed A Dream' from Les Mis - but we never got Madonna's 'You'll See'."

However, the star insisted that the show will be just as powerful without the track as it deals with some of the more emotional aspects of her upbringing, including when doctors told her parents that she was deprived of oxygen as a new-born.

Boyle added: "Why do I cry at that? Because that's the reality.That's when the doctor tells my parents, 'Don't expect too much'. He prejudged me. All the doctor told my mom was what I wouldn't be able to do, not what I could do.

"But my dad said, 'All that child needs is love - and we've got plenty of that'. It makes me cry just thinking about it, never mind seeing it on stage every night."
